Java 中的 ElasticSearch 库无法找到 AggregationBuilders.sum 方法

Question

我正在尝试在 java 中使用 ElasticSearch 的 AggregationBuilders api 来查找总和聚合。但是在使用使用此 (AggregationBuilders.sum()) 方法的服务时，它会给出以下错误：

java.lang.NoSuchMethodError:org.elasticsearch.search.aggregations.;

这是我的 pom.xml 文件

到目前为止，我已经尝试清理 .m2 并再次运行全新安装，但仍然会出现此错误。 任何帮助将不胜感激：

PS：更改 pom 后，我可以停止安装 elasticsearch 6.5，但仍在安装 6.4.3。我只想要 7.2 版本。知道如何找到导致其他版本安装的依赖项

es 模块的新 Pom

Answer 1

Spring Data Elasticsearch 3.2 不适用于 Elasticsearch 7； 3.2.0.GA 使用 Elasticsearch 6.8。

对 Easticsearch 7 的支持和适配在现在的 master 分支中，稍后将成为版本 4
